Remote phenology: Applying machine learning to detect phenological patterns in a cerrado savanna

Plant phenology has gained importance in the context of global change research, stimulating the development of new technologies for phenological observation. Digital cameras have been successfully used as multi-channel imaging sensors, providing measures of leaf color change information (RGB channels), or leafing phenological changes in plants. We monitored leaf-changing patterns of a cerrado-savanna vegetation by taken daily digital images. We extract RGB channels from digital images and correlated with phenological changes. Our first goals were: (1) to test if the color change information is able to characterize the phenological pattern of a group of species; and (2) to test if individuals from the same functional group may be automatically identified using digital images. In this paper, we present a machine learning approach to detect phenological patterns in the digital images. Our preliminary results indicate that: (1) extreme hours (morning and afternoon) are the best for identifying plant species; and (2) different plant species present a different behavior with respect to the color change information. Based on those results, we suggest that individuals from the same functional group might be identified using digital images, and introduce a new tool to help phenology experts in the species identification and location on-the-ground. ©2012 IEEE.

Ensino e aprendizagem da leitura e da escrita na educação de jovens e adultos: diálogos com a educação infantil

This article aims to present a discussion of the methodological aspects of teaching and learning to read and write in adult education, in an attempt to seek a dialogue with the Early Childhood Education by pointing convergent elements between these two instances. And, therefore, it proposes a reflection on the construction of human nature and ownership of reading and writing as a humanizing process from the perspective of historical-cultural theory advocated by Vygotsky and his collaborators. In this context it is presented a pedagogical situation in a public school for kindergarten in the state of Sao Paulo, followed by analysis from the perspective of Bakhtin in order to make some approximations in the teaching and learning of the mother tongue with adults and children.

Caracterização do desempenho de escolares com e sem dificuldades de aprendizagem em tarefas de consciência fonológica

Learning to read and write at an early stage is the process of transferring the sound form of the spoken language for the graphical form of writing, a process, a time that in our system of alphabetical called writing, the letters are graphical representations in the level of phoneme. So that this representation occurs, it is necessary that the individual already can of some form perceive and manipulate the different sonorous segments of the word. This capacity of perception directed to the segments of the word calls Phonological Awareness. Thus, it was established had for objective to verify the pertaining to school performance of 1ª to 4ª series with and without of learning in Tests of Phonological Awareness. Fourth children with age average of 9 years and 3 months without learning disabilities had been submitted to the Protocol of Phonological Awareness (CIELO, 2002) using of this instrument had participated of this study 80 pertaining to school of both only the phonological tasks. The data received from quantiqualitative approach whose results were extracted inferences. The statistically significant results occurred in the tasks of Realism Face Detection, Syllables, Detecting Phonemes, Phonemic Synthesis and Reversal Phonemic. Based on the results we observed that children without learning difficulties performed better on all tasks mentioned above

A infância na escola: aprendizagem da leitura e escrita como determinante do desempenho escolar

Mastering reading and writing brings itself social, cultural political, economic, cognitive and linguistic consequences to the learner. Soon, those who do not acquire that knowledge are excluded from the sphere of literate society. Considering this, the objective of this study was to discuss the relation between learning to read and write and in this sense, think about academic performance of students/ children, and to discusses the conceptual advances in literacy area of the permanent necessity to transport them to the teaching practice starting with questions about knowledge, attitudes and pedagogical interventions necessary for literacy teachers and that can serve as a basis for directing the training processes of teachers and to a better understanding of school performance.

A literatura no Ensino Fundamental - anos iniciais: entre o prazer emancipatório e o escolar pragmático

The Children's Literature is an invaluable tool for human formation, ethics, aesthetics and politics, as well as serves as an instrument for the formation of interdiscourse and transforms teaching procedures of text written production. Then, the investigation of how the literature is being worked in school. Therefore, in this work, constitutes the general objective, to investigate how the teaching of Children's Literature is organized in the early years of elementary school and if that organization promotes the development of literary literacy of the student, and language skills written and the reader behavior, making it critical on several topics. The question that served as a north to the research was the following one: is Teaching Children's Literature, in the early years of elementary school, organized to develop the literary literacy while acting as a catalyst tool for learning to read and write? Have been established the following objectives: a) describe how the teaching of children's literature is organized (teaching routine) in the 1st, 2nd, 3rd, 4th and 5th years of elementary school ; b) identify the literary genres that have worked in each school year, describe how they are worked out, analyze whether this work is related to the teaching of writing and the nature of that relation ship; c) verify if the Children's Literature teaching procedure seeks ways to articulate literary activities with the establishment of the interdiscourse as content for writing the textual production. The methodology that was included was the field research, from a qualitative interpretation approach and it had as direct data source the natural environment in which it was developed the teaching of Children's Literature. The work presents data results analyzed according to the concepts of Aesthetics of Reception (Iser, 1977; Jauss, 1977), and the functions of Literature, according to Candido (2000), Yasuda (2004), among others. From the results were extracted
